Zooming interface works really well. For example, I like that when zoomed out tickets of a section are grouped together. But performing is a bit slow with a cold client-side cache.

Any you particular reason you chose SVG over other alternatives (eg. tiled bitmaps)?

Thanks, in regards to the slowness, what browser were you using?

The stadium itself is actually tiled bitmaps, we're using Raphael/svg for the section/row highlights. It would have been great to use vector graphics the whole way, for one it would have given us continuous zooming instead of the predefined levels we're doing now, but the performance just isn't there yet in IE.
